Dressed for Survival

We would all be in trouble, right? Well, it’s a good thing we aren’t the decorator crab. In order to camouflage themselves from predators, they decorate their shells with whatever they find in their surroundings, resulting in quite the unique style! Can you spot the crab in this photo?

If you’ve ever found yourself wishing you could blend into the background, you may be a bit jealous of these crabs.

“There are nearly 700 species of decorator crabs around the world—about a dozen of them in California, where they live in tide pools and kelp forests. They camouflage by decorating their heads, or their entire bodies depending on the species, with pieces of seaweed, anemones or other materials around them, which they attach securely to a natural Velcro that grows right on their bodies.” 1

Also, for a closer look at a few decorator crab species, here’s a quick informational video from KQED San Francisco presented by PBS!

“Decorator crabs demonstrate a remarkably prescient instinct to be able [to] process the information required to successfully camouflage themselves to match their preferred habitat. Unlike the typically fast-scuttling crabs of the mainstream, decorator crabs move at a deliberately slow pace to reduce being noticed. 3“

Similarly, here’s one species, Leptopsia setirostri, sporting an array of carefully selected zoanthids that are now growing on its exoskeleton! 4” Thanks to Coral Morphologic for creating such stunning footage of underwater life!
